While the world has been fretting about Justin Bieber’s potty antics his ex-lover Selena Gomez has come clean and admitted she spent last month secretly holed up in rehab.

In a shock admission, the 21-year-old former Disney star confirmed she slinked off to the Dawn at The Meadows recovery centre in Arizona last month for two weeks but insisted she didn’t have a substance abuse problem.

Her team revealed the news in a statement that confirmed: ‘Selena voluntarily spent time at Meadows but not for substance abuse.’

But pals say the Come & Get It songbird is back on song after some TLC.

The rehab facility is famous for treating young people between 18 to 26 years old who are ‘struggling with emotional trauma, addiction or dual diagnosis concerns’.

Insiders say her parents Ricardo and Amanda bundled her off to get cleaned up on January 5 amid fears a spate of partying was about to sink their daughter.

‘Her friends and family became increasingly worried that there might be a serious problem with Selena,’ said an insider.

‘Particularly, her parents. The partying was, at times, wild. They wanted to help her — and they very much encouraged her to go to rehab. Others very close to her also urged her to seek professional help.’

The source continued to RadarOnline: ‘It’s important to remember that Selena had worked in Hollywood non-stop for six years. She was exhausted. Selena was smart enough to understand that she needed to take control of her life.

‘It just got to a point where she needed to get out of Los Angeles, get away from “the scene” and the pressures of Hollywood, to also get away from those who had, admittedly, become a bad influence on her.

‘Selena needed to take the opportunity to work on herself. She realised she needed help.’

Her private battle mirrors the growing concerns for her famous ex-lover Justin Bieber, who denied in an online rant last year that he needed rehab despite growing concerns and claims about marijuana use, drug-driving arrests and partying with strippers.

As for Gomez she canned her scheduled tour of Australia this month to ‘spend time on [herself]’.

And the brunette beauty is now said to be doing well.

A pal said: ‘Selena is now happy and very healthy and already getting back to work.’

She admitted her woes as she prepares to release her new clothing line for streetwear label Adidas NEO next week.

Gomez is the latest former teen star to be sunk by young Hollywood fame after High School Musical actor Zac Efron, 26, checked in last year while Camp Rock actress Demi Lovato, 21, admitted she was a drug addict.
